背棘 (总数) : 15 - 16; 背的软条 (总数) : 10 - 9; 臀棘: 3; 臀鳍软条: 9; 脊椎骨: 29. Moderately convex dorsal head profile, short snout, terminal mouth and broad bands of contiguously set teeth. Distinguished from males of all species of Neochromis by having enlarged cephalic pores, and large scales on the lateral chest surface, gradually changing to small ones only at the level of the ventral fin insertions. Differs further from N. simotes by having a deeper body (38.4% SL vs. 34.0-35.7), a shorter (26.9% HL vs. 30.8-32.5) and narrower (31.7% HL vs. 35.4-37.7) snout, smaller preorbital depth (14.9% HL vs. 16.8-18.7); larger eyes (30.9% HL vs. 27.1-28.7), a shorter (30.1% HL vs. 30.8-33.1) and narrower (27.7-% HL vs. 32.8-34.4) lower jaw, subequally bicuspid crowns to the teeth in the outer rows, fewer inner tooth rows in both jaws (5), larger scales on the occiput, cycloid scales on the caudal part of the dorsum, larger scales on the chest, and the lack of small cycloid scales on the anal/genital region (Ref. 27668).
一般中凸的头部背面轮廓 , 短吻,口部端位且邻近固定齿的宽的地带。 与 Neochromis 的所有种的雄性在侧面的胸表面上借着具有增大的头部孔 , 与大的鳞片,逐渐地只有在腹鳍嵌入的水平变成较小的区分了。 藉由有一个进一步不同于 N. simotes 比较深的身体 (38.4% SL vs.34.0-35.7) ，一个更短的 (26.9% HL vs.30.8-32.5) 与更狭窄的 (31.7% HL vs.35.4-37.7) 吻又比较小的眶前骨深度;(14.9% HL vs.16.8-18.7) 比較大的眼 (30.9% HL vs.27.1-28.7) ，一個更短的 (30.1% HL vs.30.8-33.1) 與更狹窄的 (27.7-% HL vs.32.8-34.4) 下頜, 在外部的列中幾乎相等雙尖的冠到齒, 比較少的內部齒列雙顎內 (5), 在後腦部上的較大的鱗片 , 在背面的尾鰭部份上的圓形的鱗片 , 在胸上的較大的鱗片 , 與缺乏小的圓形鱗片那之上肛門的/生殖的區域.(參考文獻 27668)
Inhabits rocky and shallow areas of the littoral zone (Ref. 4983). In the lake H. nigricans has been observed to graze on algae from rock surfaces (Ref. 558).
栖息于海滨区域的岩石与水浅区域。 (参考文献 4983) 在湖 H. nigricans 中已经被观察啃食藻类从岩石表面。 (参考文献 558)
